SSH CONFIGURATION (ROUTER & SWITCH) ON CISCO PACKET TRACER

Hello, today we are going to configure SSH (Secure Shell) to our Routers and Switches. Please see the topology below ;

Image 1 : General Topology

In the topology you may see I choice to do vlans to make it little bit harder then simple ssh configuration please see here my previous entry about vlans.

Very first action we take is to get into Router or Switch CLI and give them a hostname and banner (banner is optional).

Second step is that we configure an IP address to the defaul vlan which is vlan1 ;

Then configuring user name, domain name and crypto key rsa;

Also add the enable password to the username and domain name section ;

• SW0(config)#enable secret 12345 → (any password you think is strong)

After that we will configure the Line configuration and trnasport the SSh to this Connection type which will provide us a secure connection the important part here is to type login local ;

We are pretty much ready here ;

After configuring your vlans and giving ip to the devices like PCs Routers you may try SSH to this switch you may see the image below ;

You may pretty much implement the same process to the Router and establish a connection from anywhere securely,
